COKBINATIDN RADIO AND PHONDGBAPE AP PARATUS.

Application led January a valvular member wherebythe megaphone.

-10 may be selectively utilized in connection with the radio set or the reproducing means accordingly as the valvular member is adjustably positioned. Another object is to so construct and arrange the valvular mem- 15 her as to admit of a'd ustabIy varying the volume of sound passing uito the megaphone from either radio senor thereproducih means. f

These jects are 'lishedby the con 20 struction illustrated-pm t drawings, in which; ,Fig.1L is a; vertical I accompanying I I cross section of the aratus lon the line 11 of Fig. 3; l ig. 2d is a plan viewvof the valvular memr;an Fig". ,3 an. elevation of the apparatus in section in a plane at right anglesto that of Fig. 1, a portion being bnokenaway.

: The characters appearing the description refer to parts shown in the drawings and designated thereon by corresponding n almement with t e opening 11 in the base characters The invention comprises a cabinet 1 having two compartments 2 and 3 d vided by a vertical partition 4:, each compartment having a corresponding hinged cover, 5' and 6 respectively, for closing its top. A horlzontal platform I is positioned in the upper portion of the cabinet-and extends with n both of the compartments.

the lid 5, rests the compartment 2, and a phonographic re-' producing means 9, accessible by raising the lid 6, is mounted upon the platform within the compartment 3.

.-In the lower rear part of the compartment 3 is fixed a base block 10 having a curved opening'll that extends from the top and extends through thefront face of the block where it has communicating connection with the small end of a trumpet'12, the block and trumpet forming a megaphone. The large end of the trumpet opens through the front of the cabinet in the usual manner.

A radio controller- 8, accessible by raising upon the platform within 11, 1824. Serial No. 685,528.

Upon the top of the block 10 is a horizontally movable valvular member 13 havmg an openlng' 14 extending vertically there through and which afl'ords communication between the tone arm 15 of the reproducing means and the opening 11 of the megaphone when alined therewith. The top and-bottom surfaces of the valvular member are faced with corresponding sheets 16 of felt that have sliding contact respectively with the bottom of. the platform 7 and the top of the block 10 so that sounds that may be caused by vibrations of the valvular member are'muffled. Except at the opening 14, the top of the valvular member is fiat and closes communication between the tone arm and negaphonemore or lesscompletely according to the extent the opening 14; is positioned out of alinement therewith, and thus the volume of sound admitted to the megaphone from the r producing means may be The valvular member haselso a curved opening 17 that extends from one of its ends and through the bottom thereof at' a point a art from the vertical ppening 14:, and on t e corres nding mounted t e loud speaking unit 18 of the radio set .which unit has communication through the opening 17 with the megaphone whenthe said 0 e'ning 17 is positioned in block. The unit has electrical connection with the'controllerby means of a slack cable 19 WhlCh admits, of movement of the valvular member without disturbing the connection.

I An operating bar 20 is fixed on the valvular member 13, one end of which rotrudes through the adjacent end of the ca inet, and the otherend of which extends throu h the partition 4 into the compartment 2. pivoted lever in the compartment 2 has operable connection with the bar 20 at the correspondin end thereof, and the protruding end of t e bar is provided with a knob 22 by which the bar is manipulated in moving the valvular member to selectively establish communication between the radio receiving set or the phonographic reproducing means, and the megaphone. v

As the valvular member is provided with distinct and separate openings, and the re-. spective connections madggherethrough with the radio unit and the reproducing means,

end of the member is are entirely individual, the openings may he fashioned and of such'extent as is found most suitable in each instance.

'.'Wiiet I claim is 1, A megaphone appliance for a phonograph including a tone-arm and a radio ap eras-us .inciudin e receiver com )risin a P stationary base for said tone-arm; a fixed" end trumpet member selecigively eccordingly as said valvular member is posibloned.

2. In combination, a radio receiving mechanism, a phonograph mechanism, .a sound waive amplifier interchan 'eablycooperab le with said mechanisms, afilock hav ing a through passage andscurVed pas sage entering one side andieaV-in the bottom thereof, and means for'shi ting said block in one direction 'to connect sald I' e ceiving mechanismwlth said amplifier through said curved passage and in the 013-," posite direction to connect said phonograph with said amplifier through said through passage.

In 'test1mony whereof Infiix my signa- EARL v; HUGHES, I
